QUESTION NO: 7
Which of these can be used to authenticate the IPsec peers during IKE Phase 1?
A. Diffie-Hellman Nonce
B. pre-shared key
C. XAUTH
D. integrity check value
E. ACS
F. AH
Answer: B
Explanation:
Internet Key Exchange (IKE) executes the following phases:
+ IKE Phase 1: Two IPsec peers perform the initial negotiation of SAs. Phase 1 generates an
Internet Security Association and Key Management Protocol (ISAKMP) SA, used for management
traffic. Public key techniques or, alternatively, a pre-shared key, are used to mutually authenticate
the communicating parties. Phase 1 operates in either Main Mode or Aggressive Mode. Main
Mode protects the identity of the peers, Aggressive Mode does not.
+ IKE Phase 2: SAs are negotiated by the IKE process ISAKMP on behalf of other services, such
as IPsec, that need encryption key material for operation. IKE Phase 2 is used to build IPsec SAs,
which are for passing end-user data. Additional service negotiations occur in IKE Phase 1, DPD,
Mode Config, and so on
